Bioprinting of heterogeneous and multilayered cell-hydrogel constructs using continuous multi-material printing and aerosol-based crosslinking

Abstract

Summary: Bioprinting is a powerful biofabrication technique that mimics physiological environments and functions. Here, we describe a protocol to set up a continuous multiple-material bioprinting system that can replicate structurally complex and biologically functional microphysiological systems such as a tumor microenvironment. Although this bioprinting system uses a limited crosslinking agent, it is a versatile and advanced continuous multi-material printing technique.For complete details on the use and execution of this protocol, please refer to Lee et al. (2021).
